PS1.3 vs. PIC767

How does PS1.3 compare to PIC767 in terms of flight model and
simulation of the systems?

How does PS1.3 compare to PIC767 in terms of flight model and
simulation of the systems?

first of all, PS1 simulates a 747-400 while PSS767 simulates, as the
name suggests, a 767. two very different airliners. one has 4 engines,
the other has only 2.

in PS1, all the important systems are there, and they work exactly as
they do in the real mccoy.
the flight model is accurate enough to give performance data (like climb
rate, fuel consumption,...) within less than 4% of the original. see
